Since about 2am (about 5min after the lockloss of the night), We have been getting the following TCS Alarm:

"No TCSY chiller flow"

• This corresponds with a RED CO2Y on the Ops Overview, which leads to LASER STATUS Not Ready for the TCSy CO2 Laser.
• Trends show the CO2 Power Supply Current dropping from 20 down to ~0.
• Laser Temp dropped from a steady 24degC down to a sawtooth signal between 20-22degC.
